Tank FAQ

In this post you will find everything you need to know about our ever expanding range of Hydraulic Oil Tanks and Combination Tanks.

What type of tanks are available from Bailey Ltd?

We can manufacture all types of tanks for diesel and also hydraulic oil. We stock generic tanks but also offer a bespoke tank design service to meet your requirements.

What is the difference between a hydraulic tank and a combination tank?

A Combination Tank is used on a vehicle when there isn’t sufficient space on a chassis to fit a hydraulic tank, so the original fuel tank is removed and replaced with a tank that has two sections – one for Oil and one for Diesel
A Hydraulic Tank would be fitted in an existing space on a vehicle chassis to contain Hydraulic Oil only

What types of applications can these tanks be used for?

The purpose of the tanks are to use tipping gear, which can be used for many types of work including tipping, tip/walking floor, ejector trailer and tipper-tanker.

Fuel tanks can be used for vehicles to increase fuel capacity and also to run diesel engines on trailers

How do I know what size tank I will need?

A combination tank would usually be on a maximum capacity basis to ensure as much fuel as possible for enabled. Normally we work around the 190 Litre mark for tipping gear, but can happily advise on any requirements you many need for different applications and we could also advise and measure your vehicle to accommodate a tank fitment

What type of tank do I need?

This depends on what kind of work you are doing. Usually, if you have a gap on the side of your chassis we would manufacture a side mounted tank. The other options are combination tank to replace the fiel cell or we can offer a rear of cab option depending on the position of your fifth wheel

Do Bailey Hydraulic Tanks come with a guarantee?

Yes, as long as the tank has been fitted correctly and used for the intended purpose of the design they come with a 2 year warranty

What are Bailey tanks made from?

Our tanks are made from Transport 5251 Grade Aluminium – cut, folded and welded in our workshop to your requirements

How are tanks fitted to the vehicle?

All tanks are supplied with black mounting brackets and straps with rubbers pre-assembled. Side mounted tanks are bolted to the side rail of the chassis, rear of cab tanks are clamped or bolted to the top of the chassis (depending on the vehicle type)

Do you supply a fitting service?

Yes, we can fit all types of fuel and oil tanks for you. We are also able to add a range of fittings to your requirements such as alloy bosses for 1/4″ bsp to 3″ bsp, level gauges and tank mounted return filters if required

What is the best way to maintain a tank?

The most important factor is to ensure the straps are tightened periodically to 55-60nm. We recommend this is done weekly. We would also recommend you replace any perished or slit rubbers to straps or brackets and ensure the breathable cap is kept in a good condition (keep it clean so the tank can breathe when in use)

What else can you manufacture?

We can also manufacture combination tank toolboxes. These can either be hydraulic or fuel tank toolboxes

Do you offer painting/powdercoating options?

Yes, we offer a range of options for personalising your tank – please just contact us to discuss your requirements
